India’s human spaceflight mission Gaganyaan achieved a crucial milestone with the successful qualification-level load test of the Drogue Parachute on February 18, 2026.
The test was conducted at the Rail Track Rocket Sled (RTRS) facility of Defence Research and Development Organisation located at Terminal Ballistics Research Laboratory, Chandigarh.
Institutions Involved
The test was jointly conducted by multiple Indian space and defence organisations:
- Vikram Sarabhai Space Centre
- Aerial Delivery Research and Development Establishment
- Dedicated teams of TBRL
This collaboration highlights strong inter-agency coordination between space and defence sectors.
About the RTRS Facility
The Rail Track Rocket Sled (RTRS) is a specialised dynamic test facility used for:
- High-speed aerodynamic testing
- Ballistic evaluations
- Qualification of critical aerospace systems
Such tests simulate extreme flight conditions to ensure safety and reliability.
Purpose of Drogue Parachute
In human spaceflight missions, drogue parachutes are deployed first during crew module descent to:
- Stabilise the spacecraft
- Reduce speed before main parachute deployment
The recent test simulated qualification-level loads higher than maximum flight loads, demonstrating an additional design safety margin.
Significance of the Test
- Validates India’s capability in high-strength ribbon parachute design and manufacturing
- Enhances crew safety in the Gaganyaan mission
- Showcases TBRL’s advanced testing infrastructure and expertise
The achievement strengthens India’s preparedness for its first human spaceflight.
